Most people start thinking about an addition the same way: the house works, the location works, but the space doesn't. Maybe it's a third kid sharing a bedroom, a kitchen that can't hold the family it feeds, or parents moving in. Moving means a new mortgage at today's rates, realtor fees, and giving up a yard and neighborhood you already like. Adding onto a house keeps all of that and fixes the one thing that's wrong. The math isn't automatic in either direction, but for a lot of families in the Sioux Falls area it can favor staying put and building.
An addition is the project where the drawings do most of the work. Roof lines, foundation, and where the new load comes down all get settled on paper — before a permit is filed, and long before anything is dug. Get that part right and the build is mostly carpentry.

Pick a time for your estimateWhen adding on beats moving
An addition makes sense when the problem is square footage, not the house itself. If you like your lot, your neighbors, and your school situation, a room addition solves the space problem without resetting your mortgage or your commute. It makes less sense when the whole layout fights you, or the lot can't take more footprint. That's the honest conversation we have at the walkthrough: what you need, what the site allows, and whether building on is actually the right answer. If it is, you get a written estimate for the real scope. If it isn't, we'll say so before anyone spends money on plans. Plumbing and electrical go to licensed partner trades we have worked with for over a decade — the same crews, on our schedule and under our accountability. One contract, one contact.
Matching the house you already have
The difference between a good addition and an obvious one is in the details that have to line up: roof pitch and shingle color, siding profile and reveal, window styles, floor heights, and how the new foundation ties into the old. In South Dakota that tie-in matters below grade too. New footings go below the frost line so freeze-thaw cycles don't move the addition independently of the original house, and the roof structure is framed for prairie wind and snow load. We draft the addition around your existing structure first, then build to that plan, so the seam disappears instead of announcing itself.
Drafting, permits, and the build under one roof
Additions fail in the handoffs: a designer draws something the budget can't build, and the builder inherits a plan they didn't price. Hols & Co handles drafting, permitting, and construction as one job. We draft plans against what you actually want to spend, submit them to the city or county depending on where the property sits, and then build what was approved. Because the person who quoted the project also runs it, changes get resolved in one conversation instead of a chain of contractors pointing at each other.

In their words
Nineteen reviews. Every one of them five stars.
Highly recommend Hols & Co. if you are looking for someone to build your deck. The whole team was excellent to work with. They were professional, respectful and communicative. They were very efficient when they were on site and kept out property clean while they worked. Solid craftmanship and the finished product is exactly what we were envisioning. We would definitely hire this crew again for future projects.
The team was great. The quality of work is fantastic. I saw their ad on social media and took a chance and contacted them. So glad I did! Wanted my back deck replaced and they did a beautiful job. Even worked Saturday because the wood for the deck didn't show up on time. Looking forward to having them back for my next project!
Hols and Co. replaced our deck with a covered and screened in deck. We are extremely pleased with the workmanship and attention to detail they put into the deck. They were a pleasure to work with and would definitely recommend them for your home construction needs. Myron H.
FAQ
Fair questions, straight answers.
Should I add on to my house or move?
It comes down to whether the problem is the space or the house. If the layout, lot, and location work and you need more room, an addition usually solves it without a new mortgage or a move. If the whole floor plan fights how you live, a whole-home renovation or a different house may serve you better. We walk the site in person and give you a written estimate, so you can compare real numbers against the cost of moving.
Do I need a permit for a home addition in the Sioux Falls area?
Yes. An addition changes the footprint and structure of the house, so it needs a building permit wherever you are. Which office issues it depends on the property: inside city limits it's the city, and outside it's the county. Hols & Co handles the drafting and the permit submission as part of the job, whether the project falls under a city or a county authority in Lincoln or Minnehaha County.
How far ahead should I plan a home addition?
Earlier than most people expect. South Dakota's building season is short, and an addition has steps that happen before any dirt moves: the in-person walkthrough, drafting, the written estimate, and permit review by the city or county. Starting the conversation in fall or winter means plans and permits can be ready when the ground thaws. Reach Hols & Co at (605) 679-5223 by call or text to get a walkthrough scheduled.
